Another Newbie here and probably Irritating some of the pros here with what seems to them....a simple question .
I just purchased a 500D and coupled with a 18 to 50mm ( i think ) and another 55 to 250mm lens. I am really curious to know whether my 55 to 250mm lens would provide me with a good, close up picture in our zoo? The distance between those animal viewing areas and the animals? Do i need higher mm lens or a TC? Cause i do not want to end up going and find out that my lens is not good enough and then start looking for a TC or farther lens.
